KYN28-12 Armoured Removable Ac Metal Enclosed Switchgear

TOONICE 11KV Ring Main Unit KYN28-12 armored removable AC metal-enclosed switchgear is suitable for 3.6-12kV three-phase AC 50Hz power grid, used to receive and distribute electric energy, and to control, monitor and protect circuits. Can be used in single busbar, single busbar sectional system or double busbar system. The switchgear complies with IEC298 "AC metal-enclosed switchgear and control equipment with rated voltages above 1kV and 52kV and below", IEC694 "Common clauses for high-voltage switches and control equipment", my country's "GB3906 3-35kV AC metal-enclosed switchgear" and DIA04 "Indoor "Ordering Conditions for AC High Voltage Switchgear", German DIN.VDE0670 "AC Switchgear with Rated Voltage Above 1kV" and other standards. And it has a complete and reliable anti-misoperation function.

Feature:

The KYN28 - 12 armored movable AC metal - enclosed switchgear (hereinafter referred to as switchgear) is a new - type product independently designed and developed by our company based on absorbing advanced domestic manufacturing technologies. It can replace various old - type metal - enclosed switchgears, such as the KYN1 - 12, JYN2 - 12 series products. This product has the following distinct advantages:

The enclosure of the product is completely assembled with bolts, which has high mechanical strength and effectively ensures the integrity and aesthetics of the product. The cabinet door is coated with plastic spraying, which has strong impact - resistance and corrosion - resistance. The product enclosure has a protection level of IP4X. (It can be changed to an iron plate according to customer requirements.)

The switch of this product can be equipped with the VD4 type vacuum circuit breaker produced by ABB, the C3 series fixed - type load switch, and can also be configured with a variety of domestic series vacuum circuit breakers (such as VS1, VH1, VK, ZN28) to replace similar foreign products.

No matter which circuit breaker is selected, the air insulation distance of its conductors can be guaranteed to be greater than 125mm, and the composite insulation is greater than 60mm. These circuit breakers all have the unique advantages of long service life, low maintenance requirements, and small size.

Usage Environment

1. Ambient temperature: upper limit +40°C, lower limit -10°C.

2. Relative humidity: daily average not more than 95%, monthly average not more than 90%.facilities.

3. Altitude: not exceeding 1000m.

4. Earthquake resistance: not exceeding magnitude 8.

5. Locations free from fire, explosion hazards, severe pollution, chemical corrosion, and violent vibration.

Structural Features of the Switchgear

The switchgear is designed in accordance with the armored metal - enclosed switchgear in GB3906 - 91. As shown in Figure 1, the switchgear consists of two main parts: a fixed cabinet body and a withdrawable component (commonly known as a handcart). The enclosure of the cabinet body and the partitions of each functional unit are connected by bolts. The protection level of the switchgear enclosure is IP4X, and when the circuit breaker room door is open, the protection level is IP2X. The switchgear can be equipped with a vacuum circuit breaker handcart or a fixed - type load switch. It has functional schemes such as overhead incoming (outgoing) lines and cable outgoing lines. The switchgear can be installed in a double - cabinet arrangement, that is, back - to - back or face - to - face double - row arrangement.

The KYN28-12 Armoured Removable AC Metal Enclosed Switchgear combines advanced features with versatile applications, making it a valuable solution for a wide range of power distribution needs.
